For enhanced safety, the front and rear seat shoulder belts of the Audi A4 Allroad have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Honda Passport doesn’t offer pretensioners for its rear seat belts.

The A4 Allroad’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Passport doesn’t offer pre-crash pretensioners.

Both the A4 Allroad and Passport have child safety locks to prevent children from opening the rear doors. The A4 Allroad has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Passport’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Audi A4 Allroad has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Passport doesn’t offer knee airbags.

The A4 Allroad has a standard Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Passport doesn’t offer a whiplash protection system.

The A4 Allroad has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Passport doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

When descending a steep, off-road slope, the A4 Allroad’s standard Hill Descent Control allows you to creep down safely. The Passport doesn’t offer Hill Descent Control.

The A4 Allroad Premium Plus/Prestige has a standard Top View Camera System to allow the driver to see objects all around the vehicle on a screen. The Passport only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the A4 Allroad and Passport offer rear cross-traffic warning, but the A4 Allroad with Rear Cross-Traffic Assist also has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The Passport’s Cross Traffic Monitor doesn’t automatically brake.

Both the A4 Allroad and the Passport have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available blind spot warning systems.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a post at 20 MPH, results indicate that the Audi A4 Allroad is safer than the Honda Passport:

	A4 Allroad	Passport
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	12 inches	15 inches
HIC	333	406
Hip Force	666 lbs.	838 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A4 Allroad the rating of “Top Safety Pick” for 2022, a rating granted to only 174 vehicles tested by the IIHS. The Passport last would have qualified as a “Top Safety Pick” in 2017.

Warranty

The A4 Allroad comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Passport’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The A4 Allroad’s corrosion warranty is 7 years longer than the Passport’s (12 vs. 5 years).

Reliability

The Audi A4 Allroad’s engine uses a cast iron block for durability, while the Passport’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

A hardened steel chain, with no maintenance needs, drives the camshafts in the A4 Allroad’s engine. A rubber cam drive belt that needs periodic replacement drives the Passport’s camshafts. If the Passport’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

To reliably power the ignition and other systems and to recharge the battery, the A4 Allroad has a standard 150-amp alternator. The Passport’s 130-amp alternator isn’t as powerful.

Engine

The A4 Allroad’s 2.0 turbo 4-cylinder hybrid produces 11 lbs.-ft. more torque (273 vs. 262) than the Passport’s 3.5 SOHC V6.

Fuel Economy and Range

On the EPA test cycle the A4 Allroad gets better fuel mileage than the Passport (23 city/30 hwy vs. 19 city/24 hwy).

Regenerative brakes improve the A4 Allroad’s fuel efficiency by converting inertia back into energy instead of wasting it. The Passport doesn’t offer a regenerative braking system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi A4 Allroad higher (5 out of 10) than the Honda Passport (3). This means the A4 Allroad produces up to 16.5 pounds less smog-producing pollutants than the Passport every 15,000 miles.

Transmission

The A4 Allroad offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Passport doesn’t offer an SMG or a conventional manual transmission.

The A4 Allroad’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Passport doesn’t offer launch control.

Brakes and Stopping

For better stopping power the A4 Allroad’s brake rotors are larger than those on the Passport:

	A4 Allroad	Passport
Front Rotors	13.3 inches	12.6 inches

The A4 Allroad’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Passport are solid, not vented.

The A4 Allroad stops much shorter than the Passport:

	A4 Allroad	Passport
70 to 0 MPH	152 feet	181 feet	Car and Driver
60 to 0 MPH	119 feet	135 feet	Motor Trend

Tires and Wheels

The A4 Allroad’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Passport TrailSport’s standard 60 series tires.

Suspension and Handling

The A4 Allroad has standard front and rear gas-charged shocks for better control over choppy roads. The Passport’s suspension doesn’t offer gas-charged shocks.

The A4 Allroad has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Passport’s suspension doesn’t offer adjustable shock absorbers.

The A4 Allroad Prestige handles at .85 G’s, while the Passport Elite pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

The A4 Allroad Premium Plus executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the Passport Elite (26.3 seconds @ .69 average G’s vs. 28.1 seconds @ .62 average G’s).

For better maneuverability, the A4 Allroad’s turning circle is .9 feet tighter than the Passport AWD’s (38.4 feet vs. 39.3 feet).

Chassis

The Audi A4 Allroad may be more efficient, handle and accelerate better because it weighs about 400 pounds less than the Honda Passport.

The A4 Allroad is 5.9 inches narrower than the Passport, making the A4 Allroad easier to handle and maneuver in traffic.

The A4 Allroad is 13.4 inches shorter in height than the Passport, making the A4 Allroad much easier to wash and garage and drive (lower center of gravity).

Cargo Capacity

A low lift-over trunk design makes loading and unloading the A4 Allroad easier. The A4 Allroad’s trunk lift-over height is 26.1 inches, while the Passport’s liftover is 32 inches.

Servicing Ease

The A4 Allroad uses gas struts to support the hood for easier service access. The Passport uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the A4 Allroad is mounted longitudinally (North-South), instead of sideways, as in the Passport. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Audi service is better than Honda. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 30% lower rating, Honda is ranked 25th.

Ergonomics

The A4 Allroad Prestige has a standard heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Passport doesn’t offer a heads-up display.

The A4 Allroad’s power parking brake sets with one touch and releases with one touch or automatically. The Passport’s parking brake has to be released manually.

The power windows standard on both the A4 Allroad and the Passport have locks to prevent small children from operating them. When the lock on the A4 Allroad is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Passport prevents the driver from operating the other windows just as it does the other passengers.

The A4 Allroad’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Passport’s rear power window switches have to be held the entire time to open or close them fully.

The A4 Allroad’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Passport’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are standard on the A4 Allroad to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Passport doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A4 Allroad Prestige has standard headlight washers to keep headlight output high. The Passport doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the A4 Allroad has standard cornering lights to illuminate around corners when the turn signals are activated. The Passport doesn’t offer cornering lights.

The A4 Allroad’s power mirror controls are mounted on the armrest for easy access. The Passport’s power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.

The A4 Allroad has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel is only available on the Passport Elite.

The A4 Allroad Prestige’s Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Passport doesn’t offer an automated parking system.
